RSS Feeds?

I would like to know what the significance of RSS feeds are and how they can help my blogs/sites!

RSS Feeds will help you in updating your visitors on the latest news on your website. One can see a latest article posted on your website on his feed reader easily

I sometimes use it so I can see a lot of my favorite websites at the same time.

to add rss feeds to your site put this on ur site:xxxx.com/feeds/posts/default
